A bacteriostatic is a compound which has the effect of preventing bacterial growth. These agents do not kill bacteria like bactericidal compounds; instead, they limit further replication of bacteria at the site where they are introduced. Several antibiotic drugs are bacteriostatic agents, with tetracyclines being a notable example.
There are two basic types of antibiotics, Bacteriostatic and Bactericidal. Bacteriostatic antibiotics inhibit the replication of bacteria, but if the antibiotic is removed then the bacteria can begin to grow again. (MIC: Minimum inhibitory concentration. Drug concentration at which bacteria growth is stopped.) Bactericidal antibiotics permanently inhibit the ability of a bacteria to replicated. (MBC: Minimum Bactericidal Concentration.
